Cannondale Synapse Carbon Ultegra Di2 Disc Road Bike 2021
Utilising a potent blend of advanced carbon materials and an endurance themed design, the Cannondale Synapse Carbon Ultegra Di2 Disc Road Bike excels in the most gruelling mountain gran fondos and the most enduring training sessions.
The frameset possesses a full carbon construction, and this material has been aligned via a specific pattern to reduce weight while remaining stiff and robust. The advanced carbon material has been formed into SAVE technology defined tube sections to afford metered levels of suspension that smooth the roughest of road surfaces. This cushioning combines with generous frameset clearance for plush and wide tyres to lower rider fatigue and increase control. The frameset sports a balanced geometry that leans towards the theme of endurance to keep the rider fresh during the longest days in the saddle but is still aggressive enough for KOM attempts and sprints towards the finish line.
A stable and dependable performance is donated to the ride by the Fulcrum Racing 600 wheelset. This aluminium rimmed wheelset has a reliable, low-maintenance build but is also light and nimble for quick accelerations and consistent climbing speeds. The Shimano Ultegra Di2 configuration electronically glides through its array of gear ratios to facilitate riding across challenging topography. At the same time, the matching Ultegra disc brakes stop with a controlled action under any weather conditions.
Discreet mounts and a removable chainstay bridge complete the spec list by allowing easy and secure installation of mudguards to protect the rider through the coldest and wettest of days.
